VISE.

Specification of Letters Patent.

Patented J an. 19, 1915.

Application filed July 11, 1912. Serial No. 708,788.

To all whom it may concern:

Be it known that I, CLARENCE P.PER1OLAT, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Vises, of which the following is a specification.

My invention relates to improvements in vises and has for its object the production of a vise in which, when in operation, the movable jaw will be locked for clamping operation, when the threaded feeding shank thereof is rotated in one direction, and in which the movable jaw will be free to move toward or from the stationary jaw when said shank of said movable jaw is rotated in the opposite direction.

A further object is the production of a vise which will be extremely simple and economical in construction and efiicient in operation.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

My invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is a vertical longitudinal section of a vise embodying my invention, Fig. 2 is a bottom plan View thereof, Fig. 3 is a section taken on line a"x of Fig. 1, Figs. 4: and 5 are enlarged views of the oscillatory nut of the device showing the same positioned respectively in operative and inoperative relations to the threads of the shank upon which the same is mounted, and Fig. 6 is a section taken on line 3 y of Fig. 5.

The preferred form of construction as illustrated in the drawings comprises a relatively stationary jaw 1 and a relatively movable jaw 2, the latter, when the vise is in use being adapted to be moved toward and from the former as will be readily understood. The jaw 1 is rigidly secured by means of screws 3 to the bench top 4 or other support upon which it is desired to mount the same.

The movable jaw 2 is carried at the outer extremity of a threaded shank or screw 5, which is slidably mounted in co-aXial perforations 6 provided in parallel flanges. or bearing portions 7 depending from the base of jaw 1. Connected with the jaw 2 are also rearwardly projecting rods or pins 8, which s'lidably engage perforations 8' provided in flanges 7, the members 8 serving, as

will be understood, to maintain the jaw 2 in operative relation with the jaw 1 preventing relative rotation thereof. The front end of shank 5 is rotatably mounted in jaw 2, the latter being locked to said shank against relative longitudinal movement by means of a pin 9, passing through said shank which engages against the inner side of said jaw. Provided at the outer extremity of shank 5 is a conventional slidable handle 10 for effecting manipulation of the former.

Rockingly mounted upon the shank 5 between the fianges or bearing portions 7 is a nut 11, the arrangement being such, as will be observed, that such flanges will lock said nut against londitudinal movement. The in terior of said nut is provided at opposite sides with screw threaded portions 12 and 13 adapted, when said nut is in one position, to engage the threads of shank 5 and so that, when the latter is rotated, the same will be fed longitudinally by reason of the engagement thereof with the threads of said nut. The interior of nut 11 is of irregular formation, the arrangement being such that, when said nut is rotated from operative position, that is from the position in which the threads thereof engage with those of shank 5, portions 1 1 and 15 of the interior surface of said nut will engage with the adjacent portions of the shank 5 so that the opposite ends of said nut will rock by gravity outwardly from the axis of the shank about an imaginary pivotal point extending transversely of the axis of the said nut to efiect disengagement with threads 12 and 13 from those of the shank as clearly shown in Figs. 5 and 6, the interior of the nut opposite threads 12 and 13 being cut away at 16 and 17 respectively to permit of this movement of the nut.

The amplitude of the oscillation of the nut is governed by lugs 18 and 18 provided at the periphery of one end of said nut adapted to engage with a stationary lug 19 provided upon the base portion of jaw 1, the arrangement being such, that, when lug 18 is in engagement with stop 19, the nut will be inoperative position relative to the shank, that is the threads 12 and 13 will be in engagement with the threads of said shaft, and when the lug 18 is in engagement with the stop 19, said nut will be in inoperative position, that is, the threads 12 and 13 of said nut will be positioned out of engage ment with those of said shank. The arrangement is such that it requires the rotation of said nut through but ninety degrees to effect the movement thereof from operative to inoperative position or vice versa. Furthermore, the construction is such, that this rotation of the nut is effected by frictional contact thereof with the shank 5 so that in the operation of the vise, when the shank 5 is positively rotated, the nut will be carried thereby, if the latter is in inoperative position, to operative position and when said shank is reversely rotated, said nut will be carried by said shank, if said nut is in operative position, to inoperative position. Thus a vise is produced which will be automatic in its operation conducing to ease and expedition in using the same.

The opposite ends of the nut 11 are beveled, as will be observed, forming vertices 20 and 21. The vertices are so arranged that, when the nut is in operative position, and the vise jaws in clamping relation, the incidental engagement of the forward end of the nut with the corresponding flange 7 will effect the pressing of the threads 12 into closer operative relation with the threads of the shank, this result being secured by reason of the position of the vertex 20 below the axis of the shank as will be readily understood. IVith this construction then, the greater the force applied to the handle 10 in effecting the clamping of an article between the edges of the clamp, the more positive and secure will be the engagement of the threads of the nut with those of the shank. Likewise, when the shank is reversely rotated to release the vise jaw 2, the incidental engagement of the opposite end of the nut with the adjacent flange 7 will cause the threads 13 to be moved out of engagement with those of the shank.

A vise of the construction set forth is durable and economical in construction, may be manufactured at a low cost and the same is of high efficiency in use.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as fall within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:
